Nikon today announced the D3S, a worthy "mid-life" upgrade to their workhorse pro D-SLR the D3. The biggest change is an upgraded sensor featuring the potential for shooting at ISOs up to a staggering 102,000. Realistically the typical ISO range seems to have been bumped up by 1-2 stops over the D3. The new sensor also captures HD Video, including in very low light conditions. The FX sized sensor retains the 12MP resolution of the D3, but adds a 1.2x crop mode for 8MP shooting with a slight telephoto effect--no doubt helpful when using those lenses which vignette with the FX sensors. It also doubles the buffer size and adds a quiet shutter mode among other nifty new features. It is expected to ship from Nikon in late November for $5199 street price. Full Press Release below...
